Low-temperature oxidation technology (the LoTOx™ technology) is available from DuPont™ BELCO® Clean Air Technologies under license from BOC. This technology has strong synergy with EDV® scrubbing for refinery applications, such as FCCU, fluid cokers, heaters and boilers.
LoTOx™ technology has been applied to various gas streams, including refinery Fluid Cat Cracking Units (FCCU), with great success. This sturdy technology, when used in conjunction with the EDV® Wet Scrubbing System, does not require any gas flow obstruction (cannot plug during heavy dust load) and can be operated continuously for long-operation campaigns. These features make it an excellent fit for FCCU applications. By combining this technology with DuPont BELCO® EDV® Wet Scrubbing System, the operator can reduce particulates, SOx and NOx, all in a single vessel. There is no additional system to operate and maintain. An open channel is maintained for the gas, and the plot space required is low and flexible.
The EDV® Wet Scrubbing System with LoTOx™ technology Advantages
No bypass required
Very high reduction for NOx, SOx, and particulate all in one vessel
Can achieve the most stringent reduction requirements
Highly reliable, multi-year continuous operation
No in-line constrictions or catalyst modules
Open vessel design for trouble-free operation
No potential for plugging
Automatic control of outlet NOx level by selecting a desired NOx outlet valve
Not affected by temperature variations
Maintains constant NOx outlet level, even through NOx fluctuations at inlet
No ammonia slip concerns
Not subject to poisoning or sintering of catalyst surface due to temperature excursions
No concerns of SO2 to SO3 oxidation
DuPont™ BELCO® Clean Air Technologies offers an array of solutions for the reduction of NOx emissions. BELCO® realizes that each plant has its own particular requirements, which in most cases dictates reaching beyond a generic solution. Therefore, DuPont™ BELCO® has the ability to offer both an SCR system and the LoTOx™ Technology, and can recommend the DeNOx system to fit your application.
